We all remember the game-changing Yamaha TY 250cc Mono-Shock trials machine featuring the single-shock rear suspension, which arrived in 1983. That model used a conventional single-cylinder, air cooled two-stroke engine but the mighty Japanese manufacturer has given the trials world a massive ‘E’ shock with its new TY model electric trials machine. It was unveiled at the Tokyo Motorcycle Show in Japan in late March. Yamaha also confirmed that its factory supported rider, trials rider Kenichi Kuroyama, will represent the Yamaha Factory Racing Team during 2018 in the FIM TrialE Cup Class. Could we have the first ever Japanese Trials World Champion?
With the pictures we have seen it all looks very new. The machine has come straight from the company’s evolving research and development programme, in which their employees are given the opportunity to work outside the conventional ‘box’ and devote up to 5% of their working hours towards new ideas and concepts.
It appears that the vision for the new TY-E model was focussed around high outputs of power from small and lightweight components, with the aim of providing an easy-to-ride, responsive but controllable motorcycle. One thing you have to bear in mind at this early stage of the machine is that it’s still a prototype and not a production model. In a statement from Yamaha, it appears that the air-cooled electric engine is housed in an exotic carbon fibre chassis, very much along the lines of the modern twostroke trials models, with the underside of the engine protected by an aluminium sump guard.
With a claimed weight of 70kg the front suspension, swinging arm and wheels, disc brakes etc, appear to be very similar to some of the ones that are standard fitting in Europe.
Yamaha TY-E key features
• A high rotation-type, compact, high-power electric motor that achieves high off-road performance with both powerful low speed torque and extended acceleration. • Sophisticated motor control technology that achieves an excellent response and a power feeling from extremely low- to high-speed ranges. • A mechanical clutch that ensures instantaneous power and control, and an electric motor and optimised flywheel that offers excellent traction performance. • A newly designed, compact, high-output battery
pack with compact and lightweight components. • Advanced CFRP monocoque frame that is at the lightest possible weight while delivering optimal rigidity and battery storage space • Extremely slim bodywork that does not interfere
with the rider.
